You may regret no lights over the cooktop. The hood itself will cast shadows down on the cooktop. Recommend consider having some type of lighting directly over the cooktop.

@kaseki Thank you! Your comments pop up regularly when I search for advice, so I definitely appreciate your voice here. Your points about tilting the baffles and collecting the grease are key.

The 2018 International Residential Code, which forms the core of most statewide building codes, doesn't require installation of a range hood over a range or cooktop (although it should, in my opinion.) While a range hood is not required, if one is installed, it needs to comply with the criteria in section M1503. UL listing is not required.

Hood inserts aren't that expensive. I'd go with a commercially-available one equipped with lights unless your food is too scary to be fully illuminated during or immediately after preparation.

Thank you for your lighting concerns! It is not that I don’t think I need lights. It’s that I think the lights in the hood are inadequate.

Once you remove the lights, it’s just a non-combustible, wipe-able, baffle holder. I might go ahead and buy one. But, I think it sounds a little bonkers to pay the asking price without even considering another option.

The way to have your capture area cake and eat it too is to use double baffle banking and put the lights in the center structural brace for the baffle assemblies (will require a lot of cleaning). As long as there is a skirt/curtain defining a capture area and sufficient air velocity within this area capture within the area should be fine. Just make the area big enough.

Now the other half of the function is containment. And this requires enough velocity to entrain all of the plumes into the baffles, including any plume portions that reflect off of structure holding the baffles and lights.
